Operator's manual. Parts book. BH 23, 24 5 5.1 Structure and function Application Use the machine only as intended, see chapter Safety, Proper use. 5.2 Functional description Principle The machine is a demolition hammer with a pneumatic percussion system. It is driven by a gasoline engine. The rotary movement of the drive engine is converted into a stroke movement via a transmission and a crank gear. The piston is moved forwards and backwards by the crank gear, this compresses the air (forward movement) or generates a partial vacuum (backward movement). Due to change in pressure the percussion piston is moved forward and backwards (air cushion percussion system) and hits the tool. The hood and operator's controls are decoupled from the percussion system by a spring system. This spring system keeps vibrations away from the operator's body if he for example presses his body against the hood while working. Integrated shut-off device – RS (optional) The machine has an integrated shut-off device for connecting to an external remote cut-off. Via the remote cut-off, you can switch off several machines from a central location. This is for the safety of the operators, e.g. in track construction work. If you wish to use your machine with a remote cut-off, please contact your Wacker Neuson representative. Low Vib (optional) The machine has very low hand-arm vibration and allows fatigue-free working. 25 BH 23, 24 6 Components and operator's controls Item Designation Item Designation 1 Recoil starter 6 Supplementary handle 2 Fuel cap 7 Air cleaner 3 Handle 8 Choke 4 Gas handle 9 OFF switch 5 Tool holder 10 Fuel tap Recoil starter The recoil starter starts the engine. In certain operating situations, e.g. when ramming in posts and grounding rods, it can be advantageous to change the traction direction of the recoil starter, i.e. the position of the recoil starter should be different to the standard position.

Control of hydrocarbons and oxides of nitrogen is very important because, under certain conditions, they react to form photochemical smog when subjected to sunlight. Carbon monoxide does not react in the same way, but it is toxic. Wacker Neuson utilizes lean carburetor settings and other systems to reduce the emissions of carbon monoxide, oxides of nitrogen, and hydrocarbons. The U.S. and California Clean Air Acts EPA and California regulations require all manufacturers to furnish written instructions describing the operation and maintenance of emission control systems. The following instructions and procedures must be followed in order to keep the emissions from your Wacker Neuson engine within the emissions standards. Tampering and Altering Tampering with or altering the emission control system may increase emissions beyond the legal limit. Among those acts that constitute tampering are: •Removal or alteration of any part of the intake, fuel, or exhaust systems. •Altering or defeating the speed-adjusting mechanism to cause the engine to operate outside its design parameters. Problems That May Affect Emissions If you are aware of any of the following symptoms, have your engine inspected and repaired by your servicing dealer. •Hard starting or stalling after starting. •Rough idle. •Misfiring or backfiring under load. •Afterburning (backfiring). •Black exhaust smoke or high fuel consumption. Emission Control System Information Replacement Parts The emission control systems on your Wacker Neuson engine were designed, built, and certified to conform with EPA and California emissions regulations. We recommend the use of genuine Wacker Neuson parts whenever you have maintenance done. These originaldesign replacement parts are manufactured to the same standards as the original parts, so you can be confident of their performance. The use of replacement parts that are not of the original design and quality may impair the effectiveness of your emission control system. A manufacturer of an aftermarket part assumes the responsibility that the part will not adversely affect emission performance. The manufacturer or rebuilder of the part must certify that use of the part will not result in a failure of the engine to comply with emission regulations. Maintenance Follow the maintenance schedule. Remember that this schedule is based on the assumption that your machine will be used for its designed purpose. Sustained high-load or high-temperature operation, or use in unusually wet or dusty conditions, will require more frequent service. OXYGENATED FUELS Some conventional gasolines are being blended with alcohol or an ether compound. These gasolines are collectively referred to as oxygenated fuels. To meet clean air standards, some areas of the United States and Canada use oxygenated fuels to help reduce emissions. If you use an oxygenated fuel, be sure it is unleaded and meets the minimum octane rating requirement. Before using an oxygenated fuel, try to confirm the fuel’s contents. Some States / Provinces require this information to be posted on the pump. The following are EPA-approved percentages of oxygenates: ETHANOL - (ethyl or grain alcohol) 10% by volume. You may use gasoline containing up to 10% ethanol by volume. Gasoline containing ethanol may be marketed under the name “Gasohol”. E85 fuel should never be used, as it is an alternative fuel containing 85% ethanol, 15% gasoline. MTBE - (methyl tertiary butyl ether) 15% by volume. You may use gasoline containing up to 15% MTBE by volume. Emission Control System Information METHANOL - (methyl or wood alcohol) 5% by volume. You may use gasoline containing up to 5% methanol by volume, as long as it contains cosolvents and corrosion inhibitors to protect the fuel system. Gasoline containing more than 5% methanol by volume may cause starting and/or performance problems. It may also damage metal, rubber, and plastic parts of your fuel system. If you notice any undesirable operating symptoms, try another service station, or switch to another brand of gasoline. Fuel system damage or performance problems resulting from the use of an oxygenated fuel containing more than the percentages of oxygenates mentioned above are not covered under warranty.
